Tanah Datar W Sumatra plans new sabo dams to prevent future floods

The Tanah Datar District Government in West Sumatra, Indonesia, is renewing its request for funding to rebuild sabo dams damaged by flash floods. The re-proposal, slated for 2026, specifically addresses a damaged structure in Jorong Duo Koto, Guguak Malalo Village, South Batipuh Sub-district.

Infrastructure Needs and Disaster Recovery

This request builds on a previous proposal for three additional sabo dams impacted by the Mount Marapi cold lava flood disaster. The total cost for these three dams is estimated at Rp249 billion (approximately US$14.8 million), and construction is anticipated to begin soon. The proposed locations for these dams are in Batang Lona, Batang Anai, and Batang Pagu-Pagu.

Did You Know? The construction of these sabo dams is intended to address critical infrastructure needs related to water resources.

Critical Infrastructure for Local Communities

According to Eka Putra, the Head of Tanah Datar District, the sabo dam in Guguak Malalo is particularly important. Local residents depend on the Batang Malalo River for essential needs, including irrigating rice fields, obtaining drinking water, and maintaining community sanitation systems.

The collapse of the sabo dam in Jorong Duo Koto occurred in late November 2025 following a flash flood event. Village Head Mulyadi reported that three locations within Guguak Malalo Village were affected by flooding, highlighting the need for preventative measures.

Expert Insight: The repeated need for sabo dam repair and reconstruction underscores the vulnerability of infrastructure to natural disasters and the importance of proactive disaster mitigation strategies in regions prone to flooding.

Ongoing Concerns and Potential Next Steps

Currently, debris – including rocks, wood, and sand – is accumulating at the floodgates in Jorong Duo Koto. This buildup raises concerns about the potential for further disasters if not addressed. Construction of the new sabo dams could control water flow, particularly during the rainy season.
